Don't know if its a petrol .

Cheers grit,but its not timing tools i am after,its the timing marks on the chain i am after

are there marks on the chain - didnt think there was?? only on the gears.

Crankshaft set a tdc fip pump locked and the cam locking tool and pin for chan tensioner what more do you need number one cylinder closed .

I.ve read that there are coloured marks on the chain to tie onto the marks on the crankshaft sprocket and the fip sprocket is that not the case then,

Bright links on bottom chain. Set engine at TDC number one firing (lock with timing pin) line bright links up with marks on crank sprocket and FIP sprocket. Some FIP sprockets will be marked 4 or 6. Line up with 6. 4 is for the four cylinder engine. Cam sprocket has no marks. With engine set as said fit cam using special holding tool. Then torque bolt.

Why do you need to remove the timing chain, I thought they were supposed to last the engine's lifetime?

When new try finding them 109k later

If one breaks at speed that is the end of the engines lifetime. If you know what i mean.

As in the pistons and valves just.. crash?
Fair, what's the recommended change interval? Much longer than a belt I presume?

Only until they become slack and wear the tensinors the bores will last longer than the chains .

Did the head to cure an oil leak on mine at 117,000 miles. Bottom chain was passable top one was knackered. Tensioners had no wear to speak of.

Cam chain had bad toothache on a couple of links. A couple of mill on one maybe a mill on the other. Bottom chain was ok. Crank sprocket ok primary on FIP sprocket ok. Secondary on FIP sprocket slight wear, cam sprocket slight wear. Not a mark on either tensioner.

Think mine were a bit more gone than that as refit of fip and two full turns allowed teeth to jump .

As long as you turned engine correct way they must have been pretty knackered to jump, turning it backwards more than a tiny amount to get timing pin in is a no no.

Cheers,wammer,s is there any other way to line chain up if there are no bright links on the chain

Put chain on crank sprocket count twelve links from mark on that, and put index mark on FIP sprocket pointing at twelfth link .
